RootViewController.h
#import <UIKit/UIKit.h> @interface RootViewController : UIViewController <UIActionSheetDelegate> @end
RootViewController.m
//点击任何处，弹出UIActionSheet
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UIActionSheet *sheet=[[UIActionSheet alloc]initWithTitle:@"标题" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil, nil];
// 逐个添加按钮（比如可以是数组循环）
[sheet addButtonWithTitle:@"Item A"];
[sheet addButtonWithTitle:@"Item B"];
[sheet addButtonWithTitle:@"Item C"];
// 同时添加一个取消按钮
[sheet addButtonWithTitle:@"Cancel"];
sheet.cancelButtonIndex = sheet.numberOfButtons-1;
[sheet showInView:self.view];
}
